Asus ROG Strix x-470 f stuck on white led

[ChristTheGreat]

Hey guys!

So my computer is giving me headache right now. Everything was working fine yesterday and this morning, no display:

AMD 3700x stock
2x 16gb Corsair LPX 3200
Asus Strix x-470F @Version 5406
Asus ROG Strix RX5700
PSU Evga SN 750 g2

When I boot the computer, I am stuck at the white led (VGA).

Here'S what I tested:
-clear CMOS
-Remove ram, got orange led (ram failure)
-Put back 1 ram, white led
-Remove GPU, pu a GT 730 from my server, white led
-Tested RX5700 in second PCI-E slot, white led
-Tested my PSU, voltage seems all fine from my PSU tester (I have no other PSU for a real test, the only one I have is a 300w sparkle with 1x 4 pins PCU and no PCI-E connector)
-Removed all USB or things connected to the computer.

And now, I am still stuck at the white led. Anyone got this board and already had this issue? I'll try reseat CPU again!
I'll try to grab a good psu for testing (I don't want to unmount all from my server xD , but I think the board is dead, and that will result in a 2-3 days for having an RMA Number, 2-3 days for sending the parts, and 1 or 2 weeks for getting back a new motherboard :/ (thank you Asus for no advance replacement)

Any help or test maybe I forgot, would be appreciated.

Oups, wrong thread, wanted to post in Motherboard

Remove dGPU, use iGPU on the processor and see if that works.

If so, update bios/refresh from there.

There is no iGPU on a 3700x :/ so I can't use the onboard port for this.

Have you got different Ram you can try?

Ooof... I thought intel for some odd reason.

Yikes...does that board have bios flashback capabilities? I'd try that and flash to the latest BIOS... lots of stability and compatibility enhancements according to the notes.

I'd try reseating the CPU for sure. Also, try building the system on a cardboard box to see if it is, for some weird reason, a grounding issue.

Buy the cheapest compatible APU (with iGPU) and test with it? That way you can see if it is the CPU or the motherboard. If it boots with dGPU and APU that means the CPU is bad with PCIe lanes. But if it will only boot to iGPU then the board is bad.

I reseat the cpu, not working.

So I didn't want to, but I removed my 3600x from the server(by a chance), put a 350w psu, gt730, tested, and boom, it Works..

So, I have a dead cpu wow first time ever!
